What We Fix
We repair professional gas and dual-fuel ranges, including sealed-burner cooktops and convection ovens. On a dual-fuel range, that means both the gas cooktop and the electric oven, which are diagnosed separately. Our range repair work in Newtown Square covers everything from a routine part failure to a full sealed-system diagnosis, and parts needs and availability are confirmed after model-specific diagnosis.
Common Range Repair Problems
- A burner that clicks but will not light
- Weak, uneven, or lifting flame
- Oven slow to preheat or off calibration
- Oven not heating on bake or broil
- A grinding or noisy convection fan
- An oven that will not hold temperature
- A range door that will not seal
Typical Causes
Most range problems trace back to a manageable list of components. Here is what we most often find behind each symptom:
- Corroded or wet spark igniter. The burner clicks but does not light
- Clogged burner cap or port. The flame is weak, uneven, or lifts off the burner
- Weak oven igniter. The oven is slow to preheat or does not reach temperature
- Failed oven temperature sensor. Baking drifts off calibration
- Failed bake or broil element (dual-fuel). No heat on bake or broil
- Worn convection fan motor. A grinding noise during convection cooking
Symptom and Repair Guide
| Symptom | Likely Cause | What We Do |
|---|---|---|
| Burner clicks, no light | Corroded igniter or clogged port | Replace the igniter and clean the burner |
| Weak or uneven flame | Burner cap alignment | Clean and reseat the burner cap |
| Oven slow to preheat | Weak igniter or sensor | Test the igniter draw and replace the fault |
| Grinding during convection | Convection fan motor | Replace the fan motor |
A Gas Smell Is Different
If you ever smell gas at the range, shut off the supply, ventilate, and do not operate the appliance. That is an urgent safety issue, not a routine repair. For a burner that simply will not light, the fix is usually a corroded igniter.
